Prime Minister John Key this morning said he would not be offering a retraction or apology to cameraman Bradley Ambrose.
On Friday, lawyers for Mr Ambrose wrote to representatives of Mr Key, senior minister Steven Joyce and the National Party, asking for an apology for what they claimed were "highly defamatory" statements about Mr Ambrose.
On Tuesday, the High Court will hear arguments on whether Mr Ambrose illegally recorded a conversation between Mr Key and Act candidate John Banks.
Mr Key said he still believes the conversation was private but he would abide by the court ruling.
"It would be fair to say we wouldn't have taken the stance that we did unless we believed that we were right, which is that it was a private matter."
